If the cursor is on a line which contains references, both the reference and the referenced line are highlighted with the same color. References are automatically updated whenever their original values change.

Helping the navigation and readability, variables and references are automatically highlighted at their usages.

Press Enter, or simply navigate out from the matrix to leave the edit mode.
